In finance, risk is the chance that the return achieved on an investment will be different from that expected, and also takes into account the size of the difference. This includes the possibility of losing some or all of the original investment. In a view advocated by Damodaran, risk includes not only " downside risk " but also "upside risk" (returns that exceed expectations).  Some regard the standard deviation of the historical returns or average returns of a specific investment as providing some historical measure of risk; see modern portfolio theory. Financial risk may be market-dependent, determined by numerous market factors, or operational, resulting from fraudulent behaviour (. Bernard Madoff ). Recent studies suggest that endocrine levels may play a role in risk-taking in financial decision-making.  
Cloning takes place in several different ways. Some cloning methods present greater risk of failure or harm than others. Nuclear transfers in somatic cells, for instance, have a relatively high failure rate. This type of cloning has a 30 percent success rate. That number translates to 30 successful clones out of 1,000 tries. Lack of compatibility between nuclei and host eggs account for some failures, while improper nuclei development and lack of successful pregnancy and fertilization account for other failures. Some cloned embryos develop larger organs and body sizes than their non-cloned peers. This physiological abnormality presents problems for cloned organisms, including breathing difficulties and circulatory disorders.
Testing methods are common for every tool if you have domain knoledge means enough.
now a days in market having SAP testing,.net testing and Mainframe Testing etc..but the testing methodologies are common in software testing what ever the application is your going to apply common proceedure so dont bother about it you concentrate on concepts of testing and in which time we are going to appy these tests in application.
And the HR asking you why you choose testing ?
comparing to my Engineering degree and skills it is suitable to me and i have such politeness to work on it.
